ОТ ПРИСТАНИ ГОРОДА ВОЛГОГРАДА ОТОШЛИ ОДНОВРЕМЕННО В ПРОТИВОПОЛОЖНЫХ НАПРАВЛЕНИЯХ ДВА ТЕПЛОХОДА ЧЕРЕЗ 4ЧАСА РАССТОЯНИЕ МЕЖДУ НИМИ СТАЛО 268КМ СРЕДНЯЯ СКОРОСТЬ ДВИЖЕНИЯ ПЕРВОГО ТЕПЛОХОДА 35КМ В ЧАС НАЙДИ СРЕДНЮЮ СКОРОСТЬ ДВИЖЕНИЯ ВТОРОГО ТЕПЛОХОДА

Answer 1

268/4=67 км/ч общая скорость

67-35=32 км/ч скорость второго теплохода

Answer 2

1)35*4=140км-1 корабль прошёл.

2)268-140=128км-прошёл 2 корабль

3)128:4=32км\ч скорость 2 корабля

 

Answer 3

Calculation of the Second Ship's Speed

To find the average speed of the second ship, we can use the formula:

Average Speed = Total Distance / Total Time

We are given the following information: - The first ship's speed is 35 km/h. - The distance between the two ships is 268 km. - The time it took for the two ships to move apart is 4 hours.

Let's calculate the average speed of the second ship:

Total Distance = Distance covered by the first ship + Distance covered by the second ship

The distance covered by the first ship can be calculated using the formula:

Distance = Speed × Time

For the first ship: - Speed = 35 km/h - Time = 4 hours

Distance covered by the first ship = 35 km/h × 4 hours = 140 km

Now, we can calculate the distance covered by the second ship:

Distance covered by the second ship = Total Distance - Distance covered by the first ship

Distance covered by the second ship = 268 km - 140 km = 128 km

Now that we have the distance covered by the second ship, we can calculate its average speed:

Average Speed of the second ship = Distance covered by the second ship / Time

For the second ship: - Distance covered = 128 km - Time = 4 hours

Average Speed of the second ship = 128 km / 4 hours = 32 km/h

Therefore, the average speed of the second ship is 32 km/h.
